Happiness, Book of Proverbs

The perverse in heart come to no good, and the double-tongued fall into trouble.

+ Book of Proverbs 17, 20

[17:20] The saying employs the familiar metaphors of walking = conducting oneself (“fall into trouble”), and of straight and crooked = right and wrong (“perverse,” “double-tongued”).
